Prologo Scratch M5 PAS CPC NACK Saddle

The Prologo Scratch M5 PAS CPC NACK Saddle is built for riders who refuse to compromise between weight and long-ride comfort — a road, gravel, and XC saddle that weighs in at 146 grams while carrying a meaningful stack of pressure-management technology. The round T-shape profile encourages freedom of movement, while the anatomical geometry positions you further back on the saddle to make full use of its length — a design choice that benefits riders with limited pelvic rotation. The central PAS channel runs the length of the sit zone to reduce perineal pressure and support circulation on extended efforts. Above it, the CPC surface — a patented 3D polymer structure — adds grip without glue-like resistance, absorbs road vibration, and improves airflow to help manage heat over longer hours in the saddle. NACK rails combine carbon fibre with Kevlar and aluminium filaments, keeping weight low while maintaining the stiffness needed for consistent power transfer through every pedal stroke.
